DRILLING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 479,086, dated July 19, 1892. Application filed September 26, 1891. Serial No. 406,881. (No model.)

To all whom it may concern.-

Beit known that I, Orro SrERNoFF-BEYER, of Oarlstadt, in the county of Bergen and State of New Jersey, have invented a new andlmproved Drilling-Machine, of which the following is a full, clear, and exact description.

The invention relates to multiple drillingmachines for drilling a series of apertures in buttons or other like articles.

The object of the invention is to provide an improved drilling-machine, which is simple and durable in construction, very effective in operation, and designed to accurately drill a series of symmetrically-arranged apertures in the article.

The invention consists of a series of simi larly-revolving drills arranged in a circle, but eccentric to the centers of the articles to be drilled.

The invention further consists of a revoluble disk adapted to support a series of articles to be drilled and arranged opposite a series of similarly-revolving drills arranged in a circle and eccentric to the articles held by the said disk.

The invention also consists of certain parts and details and combinations of the same, as willbe fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters and numerals of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement with parts in section. Fig. 2 is a transverse section of the same on the line so a: of Fig. 1. Fig. 3 is a similar view of the same on the line y 'y of Fig. 1, and Fig. 4 is a like view of the same on the line 2 z of Fig. 1.

The improved drilling-machine is provided with a base A, supporting on one end a headstock B, in which are journaled a series of drill-spindles O, O, 0 and 0 arranged in a circle, as is plainly indicated in Fig. 2. The drill-spindles support suitable drills D, D, D and D respectively, and on the said spindles within the head-stock B are secured gear-wheels E, E, E and E respectively, all

in mesh with a centrally-arranged gear-wheel F, secured on a driving-shaft G, mounted to turn in suitable hearings in the head-stock B and connected with suitable machinery for imparting a rotary motion to the said shaft G, and by the gear-wheels F, E, E, E and E to the drill-spindles and the drills, so that the latter rotate simultaneously.

On the base A, opposite the drills D, D,D and D is arranged a disk or wheel H, secured on a shaft I, mounted to turn and to slide in suitable bearings held on a frame J, supported on the base A. On the outer end of the shaft I is secured a knob I for conveniently turning the said shaft for impartinga sliding motion to the same, for the purpose hereinafter more fully described.

On the wheel or disk H is arranged a series of chucks K, K, K and K arranged in a circle which is eccentric to the circle in which the drills D, D, D and D are located. Each of the chucks K, K, K or K is made conical and split into sections forming jaws, the conical part fitting into a correspondingly-shaped recess extending longitudinally in the wheel H. When a chuck is pushed out of its seat in the wheel H, then the split sections open to permit ready displacement of the article held in a recess in the front end of the respective chuck and also permit of conveniently inserting a new article to be drilled.

In order to hold a chuck K, K, K or'K in position, a spring L engages the rear end of the chuck and presses at one end against the rear face of the wheel H and with its other end on a pin L, secured to the projecting end of the chuck.

On one side of the frame J is arranged a lug N, adapted to be engaged by the rear end of a chuck when the shaft I is slid rearward, so that the respective chuck is pressed on and pushed out of its seat in the wheel H to permit its split sections to open to release the article therein and to permit of insertinga new article. As soon as the shaft is moved forward, the respective spring L on the chuck again forces the latter to its seat in the wheel.

The wheel H is provided with an annular flange 0, formed with a series of recesses O, 0 O and 0 arranged in line with the chucks K, K, K and K respectively, and adapted to be alternately engaged by the wedgeshaped part P of a lever P, )ivoted to the frame J and held in a locked position by a spring Q, as is plainly shown in Fig. 1. The lever P extends longitudinally and permits the wheel H to slide longitudinally when the shaft I is pulled, and the wedge-shaped part P permits of turning the wheel H in one direction when the position of the chucks is to be changed, for the purpose presently to be stated.

The operation is as follows: \Vhen the wheel H is in the position illustrated in Fig. 3 and the several chucks K, K, K and K are empty, then the operator, in order to start the machine, pulls on the knob I, so that the wheel H moves rearward and the chuck K is opened by abutting on the projection N. A blank button can then be readily inserted into the open chuck K, after which the operator releases the pressure on the knob I, so that the spring L on the chuck K forces the latter back to its seat in the wheel H, thereby closing the jaws and thus securely holding the button in place. The operator then gives a quarterturn to the knob I, so that the wheel H turns and moves the chuck K opposite the drill D, the position of the other chucks being correspondingly changed relative to the drills. The operator now pushes on the knob I, so that the shaft I, with the wheel H and the chucks, is moved toward the head-stock B and the revolving drill-D drills an opening in the button at one side of its center at 1, as plainly shown in Fig. 3. As soon as the aperture has been drilled the operator pulls on the knob I, so as to return the wheel H to the position shown in Fig. 1. A farther rearward pull brings the second chuck K in contact with the projection N, so that this chuck K opens and the button is inserted therein. The operator then gives a quarter-turn to the knob I and consequently to the shaft I and wheel H, so that the chuck K is moved opposite the drill D and the chuck K is moved opposite the drill D. A farther forward movement of the wheel H causes the drills D and D to drill apertures in the buttons held in the chuck K and K the aperture in the button of the chuck K being to one side of its center alongside the aperture 1, as illustrated at the left in Fig. 3,the second aperture being indicated by the numeral 2. An aperture is also drilled in the button in the chuck K at 1, as shown in the said figure. A rearward pull on the knob 1' moves the wheel H back to its normal position, and a farther rearward pull brings the chuck K in contact with the projection N, so that the chuck-jaws are opened and a button can be inserted. After the button is locked in the jaws of the chuck K the wheel H is again given a quarter-turn, so that the first chuck K is opposite the drill D the chuck K is opposite the drill D and the chuck K is opposite the drill D, while the chuck K is opposite the drill D. By

pushing the wheel H forward three apertures are drilled in the three buttons, the aperture in the button of the chuck K being drilled at 3 alongside the other two apertures 1 and 2, and at one side of the center of the button, as shown at the bottom of the wheel in Fig. 3. The second aperture is drilled in the button in the chuck K while the first aperture is drilled in the button in the chuck K After the apertures are drilled the wheel K is moved backward until the jaws in the chuck K open for the insertion of a button in the said chuck. The wheel H is then again given a quarter-turn, so that the several chucks assume the position illustrated in Fig. 3, and then on the forward movement of the wheel H toward the head-stock 13 four apertures are drilled in the four buttons namely, one aperture in the button in the chuck K at 1, two apertures in the button in the chuck K (marked 1 and 2,) three apertures in the button in the chuck K (indicated by the numerals 1, 2, and 3,) and four apertures in the button in the chuck K, (marked 1, 2, 3, and 4.) On a farther rear ward movement of the wheel 11 the chuck K is brought in contact with the projection N, so that the jaws open and the button with the four apertures drilled in it drops out of the jaws and a new button is inserted. The above-described operation is then repeatedthat is, a quarterturn is given to the wheel H, and it is then moved forward toward the headstock B-so that four apertures are drilled in the four buttons in the manner above described.

It is understood that the wheel H is locked in position after the quarter-turns have been given to it in the manner above described by the lever P dropping in the respective notches O, O, 0 and 0 formed in the flange 0 of the said wheel. The wheel is always turned at the time the flange 0 stands under the incline P, as the latter permits turning of the said wheel by the incline sliding out of the notch and the lever resting on the flange 0 until it again drops into the next following notch. The lever is sufliciently long to permit a forward and backward sliding of the wheel H without the said lever becoming disconnected from the respective notch during the longitudinal movement. It will be seen that when the wheel H is revolved or given a quarter-turn, as above described, each button changes position relative to the next drill, so that the four apertures are drilled in the button in a circle after four quarter-turns have been made, each button being operated on by each one of the drills, which are arranged in a circle eccentric to the circle in which the buttons are located.

It is understood that the device can be readily arranged for drilling two, three, five, six, or any number of articles with a corresponding number of apertures, the wheel II being provided for this purpose with a corresponding number of chucks and the head-stock B being provided with a corresponding number of drills arranged in a circle eccentric to the circle in which the chucks are located in the Wheel H.
